Applieation filed August 17, 1914. Serial No. 857.079.

Iilf) all /ufhom may Concern Beit known that l. Yixrnx'r (i. rruc,residing.r at llayton, in the county of Montpellierv and State of Ohio,have invented `certain new and useful improvements in rhvitches` ofwhich the following is a specification.

This invention relates to improvements in electric lighting apparatusfor automohilos and more particularly to a switch and wiring systemwherebyvarious combinations of lights may he. connected with the batteryor other source of energy.

@ne of the objects ot my invention is to provide a simple1l compact andVeiiicient switch together with its wiring; connections whereby thelights, in different combinahe connected with said source lenergzgy, andthe head lights dimmed when desired by connecting them in series, thusvlowering; their individual 7ooltagre and consequently reducing theircandie power.

Another object of my invention is to provide, sue-h an apparatus inwhich theI tail light must always he lighted when yany other of thelights sue-h as the side lights or head lights are being used.

Still another object of my invention is to provide contacts and movableswitch arms so Constructed as to of themselves provide stops forpositioning the switch blades in their various operative positions.

@ther and further objects will become apparent to those skilled in theart from a consideration of the following description and drawing,wherein-a lfigure tis a horizontal cross section through the dash hoardor instrument` hoard -oif'an autoinohile showingr the n'iethod otmounting my improved switch. Fig. 2 is a front elevation of said dashhoard showing@` the parts visible lo the operator. Fig. is a horizontaldiametrical sectional view through my improved switch. Fig. l is asectional view on the line 4-4 of Fig. 3, the wiring being indicateddiagrannmitically. Figi'. 5 is a sectional view on the line i--5 of Fig.il. Fig'.

'lhe rear end ol the luhes lo are headed as at 18 and at theiropposite ends they are flanged over lthus mahiiu;Y rigid connection withthe bridge plate l?. The connectingscrews it pass through the front faceof lhe instrument hoard 15 inlo the lapped opening in the luhes lo andhohl the switch in position. fit the front face of the instrument hoardl5 l have provided a dial or plate l) through which the screws 1S pass.The particular switch illustrated in Flgs. l to i3 is adapted for usewith a head light tail light oiitlil and the di'al indicates Loil", on",and dim.

l prefer to make the hod)Y part of the switch ol iilrer. halielite. orsimilar insulatinglr material which is easily molded and l'orms asubstantial hody into which the bindingr posts and contacts may hesecured. fr threaded sleeve 2() extends through the hase. part l() atits center and carries at its inner end a hearing' pin 2l oll reduceddiameter which extends into the cup openingA l2 and serves as a hearing'upon which thc switch post 22 is pivoted. rlhe, switch post passesthrough an openingr in the center ot the bridge plate 17 and is providedwith a iange 21% which underlies the inner surface oi" the plate 17securely holding the post in place. rl`wo switch arms are carried by thepost 22, the one indicated by the numeral 24 being positioned -directlylat the rear of the Harige 23 and making close Contact therethereforewith. yDirectly beyond the flange is placed a fiber washer 25 uponwhich. rests the second switch :ii-m26. T he opening in the 'switch arm26 is considerably larger than that of the pinand receives an insulatingbushing. carried by the washer 27. -A nut 28 is threaded on the innerend of the switch post and holds the arm in rigid position thereon. Thetwo switch arms 24 and 2G are disposed at approximately 90 degrees toeach other and carry on their end the 'button shaped contact points 29.The outer end of the switch post 22 lcarries a trans verse pin -30 forengagement with the slot 31 of the tubular operating key The outer endof the key 32 is provided with an arrow shaped head 33 which registerswith the indications on the dial face lll. lVhen =the key is removed theswitch is locked in the desired position and nothing projects b'eyondthe tace of the dial.

Four switch contacts indicated in general by B-,`B+, H, and C arepositioned in the base 10 at approximately 9() degrees to each other.The construction oit' the contacts is illustrated in detail in Fig. Eachcom: prises a `,tubular insert -S-l fitting tightly within an opening inthe base and centrally tapped to receive the contact screws The innerend of the tube is beveled out as at 3G to receive the buttons 29 on theswitch arms. Two other contact pins indicated in generalby letters M andN are positioned diametrically. opposite each other and comfprise solidpins 37 cup shaped at their inner ends 38. A screw terminal T isthreaded into a tapped opening in the sleeve 2O and serves as a fifthbinding post. A short strip of metal 39 joins the two contacts H and Mand a second arcuate strip 4() joins the two contacts B+ and N.

In Fig. 4 the switch is positioned with its switch blades intermediatethe contacts and a slight movement or rotation o't' the post to' dimmed.lhen the switch blades are rotated slightly to the right ot the positionindieatedin Fig. 4 the ends ot' switch blade 24 willdrop into thedepressions 44 and eut in the insulatingr material of the base. At thesame time the ends of switch blade 2 6 will drop into the depressions 46and 47 in the insulating material and at this point the switch is in theoff or neutral position.

A further rotation to the right carries the ends "of the switch blade 24against ycontacts C and B+, the ends of the switch blade 2G makingcontact with contacts H and l3-. The upper end oli` the switch bladeI 2lin 'this positionmakes contact with the insulating stop post The switchis then positioned so that the head lights and the tail light willreceive :Eull battery voltage.

The wiring terminals on the switch are all positioned at the rear tacethereof Ylor ready access. ln connecting up the switch in the lightingcircuit ot' an automobile the positive terminal ol the battery A isconnected by wire 4S to terminal B+, and the negati ve terminal ot thebattery is connected by 4a wire 49 with terminal B+; One side ol! thetail light TL is connected by wire 5() with terminal 'll and the otherside connected by wire 5l to wire 1.2 at point One side ol each of thehead lights llL and lll/ are ioined by wire'i-l, the opposite terminalof head light Hli being connected with wire 54 the' other end ot' whichis connected with wire 49 at point 52. The opposite terminal of the headlight lill is ioim-,d by wire 55 to terminal ll. Yfeed wire 5o extendsYfrom .terminal (l to point 5i on. wire 53.

lilith the switch in the central or oli position all four contact pointson the -switchblades rest in depressions in the insulating base 1() andno current llows lfrom the battery to any of the lights. Rotating theswitch post to the right to the on position throws switch blade 24across terminals C, B+ and switch vblade 2G across terminals l3, H.Current will then llow from the positive terminal of the battery Avthrough wire 4S to terminal B+ across switch blade 24 to terminal C,thence on wire 5G to wire 53, leading to each of the head lights. Thereturn from head light HL is through wire 54 to point 52', thence to thenegative side of the battery. 'The return from headlight HL is over wiretermi nal H, across switch blade 2G to terminal B+, over wire 49 topoint 52 and to the negative side ot the battery. The head lights arethus connected in parallel each 'to receive 'i'.'ull battery voltage. Atthe same time current flows Yfrom the positive side of the battery tothe switch blade 24, out through terminal '.l", over wire 50 to one sideof the tail iight from which it returns over wire 5l. to point and tothe negative side of the battery.

To dim or reduce the candle power of the head lights, the switch postrotated to its extreme left position with switch blade bridgingterminals M, N and the ends of switch blade 26 resting in thedepressions wire 55 to one side of head light HL' direct" over wire 53to one side of head light Aswitch bladel 24 and on the other side headlights being extinguished.

throughm'ire 51 to the negative side of the battery! .IVhile in thisposition the two headlights are in series with each other across thebattery and their candle power thus materially decreased, the' taillight however, receiving` full battery voltage.

In the embodiment of my invention illustrated in Figs. 7, 8 and 9 I haveshown a switch yadapted/for use in connection with a head light, sidelight and taillight outt, there being five positions of the switch. Thefirst position at the extreme left is with the head lights dim and thetail light lighted. The second position from the left is with both headlights and tail light on full voltage. VThe next position,'or centralposition,

iis withall lights extinguished. The next position to the right is with*full current flowing to head lights, side lights and tail light. Theextreme position to the'right nor the fifth position is with the sidelights and tail light receiving full voltage, the

The construction of this.. switch is substantially similar to thatillustrated in Figs. 1 to. 6 and I have indicated the `correspondingparts with the saine numerals adding a prime mark thereto. The switchblades 24. and26 instead of being positioned at 90 degrees to each otherare at an acute angle, somewhat less than 45 degrees and the insulatedswitch blade 26 is considerably 'shorter than the switch blade 24', its

end contacts rotating in a diiferent circle and upon 'different contactpoints. It will be noted from Fig. 9 that four terminals, B-l, S, C andH are positioned in the Outer circle receiving current from the switchblade 24 whereas the terminal B- is in the inner circle .receivingcurrent from switch blade 26', the central terminal T 'being positionedas in the other switch centrally and in Contact with the switch post.

The wires'leading from the head lights, tail light and battery to theswitch are positioned as in the previously described systeni and I havethereforefindicated the wires by the saine numerals with the addedexponent. The sidelghts SL and SL are p paralleled by the two wires 60and 61, feed wire 62 extending from the main wire 60 to v -wire 51 andthe second feed `-wire 63 extending from the main wire 61 to `terminalS.

The inner construction of the switch is illustrated in Fig. 7. In theupper sector :jour outer circle contacts B{-, 64,- 65 and vwith terminalS.

. engagement with the switch blade 26. These are. joined by an arcuatemetallic strip 72; An opposite pair of terminals 73, 74- are positionedin the lower sector and likewise are joined by a metallic strip 75, theterminal' 73 being joined to terminal H by strip 76. A

When the switch is in the position illustrated in Eig. 7, the oppositeends of switch blade 24 rest in depressions 77, 7 8 in the insulatingmaterial and the ends of the switch blade 26 rest in similar depressions7 9, 80. lVhen in this position all lights are extinguished. one pointto the right of the zero position,

switch blade lZ-l bridges terminals 68 and ,65 whereas switch blade 26bridges terminal B- and 74. Wlienin this position current flows from thebattery direct to each head light with fullvoltage and to the tail lightas' previously described. In addition to this the-side lights are.supplied with current, at full voltage.

lVhen the switch is rotated from zero to the left one point, the switchblade Q4 bridges terininals 64 and C', whereas switch blade 26 bridgesterminals 71, 73. When in thisposition both head lights and tail lightare supplied with full voltage and the side lights are not in circuit.When the switch is rotated from this position still further to the left,switch blade 24 bridges terminals Bl and H and the ends ot" switch blade26 rest in depressions in the insulating base. In this position 'thehead lights are connected in series and therefore are dimmed and thetail light. is given full voltage.

When the switch is rotated to the extreme right position, the sdeLlightsand tail light alone are supplied with current, the switch, blade 24bridging terminals 66, S .and

82 in the"insulat-ing base.

Having described my invention, what I claim isz-I 1.' The combination ina switch of a blade When the switch is rotated movable in th''planeparallel to one wall of the casing and having convex projectionsthereon, a contact for said blade adapted to bev engaged bysaid'convexprojections andk comprising a metallic Amember having a' switch blade 26resting in depressions 81,

through aperture, the inner end of which iS impositivclv engaged by theconvex projecltion outhe .switch blade. said aperture being threaded atits outer cud and a terminal screw taking into said threaded aperture.

2. .t .switch comprising a body part ot insulating material, a Switchblade movable in a plane parallel to one wall ot' the lasingr andhavingr button shaped projections on the ends thereof` contacts tor saidblade comprising internally threaded tubes positioned in the wall ol'said casing substantially parallel to the `switch blade with theirYinner ends flush with the inner surfacel of the wall, andterminalscrews taking into said threaded tubes from their outer ends.
